  • can't get php mail() working on Ubuntu desktop version with sendmail and postfix

    - by user36428
    I'm running Ubuntu 9.10 LAMP and trying to do a simple email test with PHP and I'm not getting any emails sent. mail("[email protected]", "eric-linux test", "test") or die("can't send mail"); I get no errors from PHP when running that script. In my php.ini file is: sendmail_path = /usr/lib/sendmail -t -i $ sudo ps aux | grep sendmail eric 2486 0.0 0.4 8368 2344 pts/0 T 14:52 0:00 sendmail -s “Hello world” [email protected] eric 8747 0.0 0.3 5692 1616 pts/2 T 16:18 0:00 sendmail eric 8749 0.0 0.3 5692 1636 pts/2 T 16:18 0:00 sendmail start eric 9190 0.0 0.3 5692 1636 pts/2 T 19:12 0:00 sendmail start eric 9192 0.0 0.3 5692 1616 pts/2 T 19:12 0:00 sendmail eric 9425 0.0 0.3 5692 1620 pts/1 T 19:37 0:00 sendmail eric 9427 0.0 0.3 6584 1636 pts/1 T 19:37 0:00 sendmail restart eric 9429 0.0 0.3 5692 1636 pts/1 T 19:38 0:00 /usr/lib/sendmail restart eric 9432 0.0 0.1 3040 804 pts/1 R+ 19:38 0:00 grep --color=auto sendmail When I run $ sendmail start it just hangs there doing nothing.

  • Problems starting autossh on boot [ubuntu]

    - by Ken
    I'm trying to automatically start an SSH tunnel to my server on boot from a ubuntu box. I have an ubuntu box that's mounted on an 18-wheeler and is networked behind an air card. The box hosts a mysql database that i'm trying to have replicated when the aircard is connected. As I can never be sure of my IP and how many or which routers I'm behind I'm connected to my replication server with an SSH tunnel. I got that working using the following command: ssh -R 3307:localhost:3307 [email protected] Now I'd like that to start whenever the box is, and be alive all the time, so I installed auto-ssh and setup this little script: ID=xkenneth HOST=erdosmiller.com AUTOSSH_POLL=15 AUTOSSH_PORT=20000 AUTOSSH_GATETIME=30 AUTOSSH_DEBUG=yes AUTOSSH_PATH=/usr/bin/ssh export AUTOSSH_POLL AUTOSSH_DEBUG AUTOSSH_PATH AUTOSSH_GATETIME AUTOSSH_PORT autossh -2 -fN -M 20000 -R 3307:localhost:3306 ${ID}@${HOST} I've tried putting this scrip in /etc/init.d/ and using a post-up command in /etc/network/interfaces as well as putting it in /etc/network/if-up.d/. In both situations the script starts on boot, but the tunnel doesn't appear to be correctly established. The script works when run manually.

  • outgoing DNS flood targeted to non-ISP hosts

    - by radudani
    Below is the specific traffic monitored at the network perimeter and originating from a user PC on Vista platform. My question is not about the effects of the flood, but about the nature of the source of it. Is this some known infection, or just an application went out of control? a standard NOD32 scan didn't find anything, as the user told me.

  • Can gnome windows (in Ubuntu) be individually themed?

    - by Peter.O
    (Yes, "individually themed" is an oxymoron, but I still want it.) I've just moved from Windows to Ubuntu Linux, and although I am enjoying this new adventure playground, I've encountered something quite unexpected... and its bugging me. It is probably because there are so many gnome apps in Ubuntu (... how strange :) This is great. and the range of available apps is excellent! ...but because of this one-stop-shop scenario, most of the windows look remarkably similar. I'm certainly not after bling-maximus, but I would like a few differentiating colours for my not-so-young eyes to help identify an app at a glance (especially in the compiz lists) ... I love compiz :) I thought it was just a bit of razzle-dazzle, and that alone would be enough, but it is actually very practical to boot. So, basically, I'm wondering if there is a way to theme individual window components on a per app basis... especially the window decoration; menu bar, etc. Thanks.

  • can't properly shutdown ubuntu and sound problem on HP mini 311 netbook

    - by Viele
    hi, I recently bought a HP mini 311 netbook. I replaced its harddrive and installed ubuntu 10.04. Since then, I have encountered some very strange problem with its sound and shutdown/reboot. At times, when I start the computer, it will have no sound, on the GUI the sound is at max, but no sound is available. This sometimes also happen after after upgrades, hibernate, and toggling the wireless radio button. Strangely, when the sound is out the device will also refuse to be shutdown. If I shutdown the computer using the GUI, it will simply go back to the log in screen without actually shutting down. If I use "sudo shutdown 0", the computer will hang on the loading screen of the shut down process. I had to force the pc to shutdown by holding the power button down. usually (probably always) after I force a turn-off then start off again. the sound and shutdown become normal. I wonder if anyone have clues regarding to the cause of this problem. This the info about the computer: 1) installed ubuntu 10.04LTS RC, later upgraded to formal released version. 2) cat /proc/asound/version == "Advanced Linux Sound Architecture Driver Version 1.0.21." however, when doing 'alsaconf' the version displayed is 1.0.23 any help is appreciated. Thanks

  • Setting up a static IP address (public) in Ubuntu

    - by ycseattle
    I have a business class internet connection and need to setup a static ip address for a machine. I did a search online and only find how to setup static local ip addresses (like 192.168..). I tried the same technique, and only setup the ip address and netmask, but after restart networking the computer could not connect to the outside world. This is what I did: 1) edit /etc/network/interfaces iface eth0 inet static address 173.10.xxx.xx netmask 255.255.255.252 2) edit /etc/resolv.conf search wp.comcast.net nameserver xx.xx.xx.xxx nameserver xx.xx.xx.xxx 3) restart network sudo /etc/init.d/networking restart Now the last step didn't report error, ifconfig shows the ip address was set, but this server cannot connect to outside world, ping google.com and reports "unknown host google.com". Any ideas?

  • Ubuntu root privs installation issue

    - by Pam
    I am a fairly new Ubuntu user (and Linux user, for that matter) and I just downloaded a program whose installer was a .sh file. Not thinking, I copied the installer to an /opt subdirectory, thinking that I was going to install the application there: sudo cp ~/Downloads/fooInstaller.sh /opt/someDir I can't remember, but I either had to use sudo because /opt required it, or I just used it without thinking, but in any case, I prefixed with sudo. Once in /opt/someDir, I executed the installer again, using sudo: sudo sh fooInstaller.sh The terminal went crazy, and a few seconds later, a graphical install wizard popped up that guided me through the rest of the process. At the end of the wizard I was prompted to launch the program, and I did, and everything was great. Until... I closed the program, and attempted to add it to my Ubuntu "panel" (the icon panel at the top of the screen). The program was installed to /usr/local/foo/theProgram, and so I specified that URL as the command in the custom app launcher. When I open the program through the panel/launcher (at the top of the screen), the program doesn't load or operate correctly. I get a lot of error messages complaining about being denied permissions. I'm assuming that this is a "superuser/installation/privs" issue, and not a problem with the application (hence this post at superuser.com instead of the application's forums), because when I launch the program from the terminal with sudo, it opens and executes perfectly fine, just like it did the first time around after the install wizard finished. I realize I'm probably going to have to uninstall the program completely, and re-install it differently. Finally, my question: After uninstalling, can I avoid all these issue by just running the installer (sh fooInstaller.sh) right out of my Downloads directory, sans the sudo prefix? If not, how do I get the program to install without root privs so that I can add it to my panel/launcher and get it executing correctly? Sorry for the long post but I didn't want to omit any details because, as I'm sure you can tell, I'm not really sure I know what I'm doing. Thanks for any help here!

  • CouchDB Errors: "undefined symbol: js_fgets" on Ubuntu 10.04

    - by MattEzell
    Hello, ServerFault Community. I have been wrestling with this problem for weeks without resolution and was hoping that someone here might be able to help. As indicated above, this is in Ubuntu 10.04 (x86) using CouchDB 0.11.0. I have build and installed CouchDB 0.11.0 from source. Everything with the dependencies and with the CouchDB install itself 'goes off without a hitch' - no errors or complaints in the configure, make or install... CouchDB seems to be running 'fine'. I can access Futon without issue and utilize all CouchDB functionality found in Futon... Unfortunately, when I attempt to use any shows/views for an installed Couch App, I get the above js_fgets error before terminal (and the Couch log) fills up with TONS of JSON. Nothing ever renders in the browser, though Firebugs reports. I have used the official instructions (paying special attention to the 10.04 instructions) and have followed pretty much every Google thread that I can find on similar issues. I have chase SpiderMonkey (and Rhino) as well as Erlang as the culprit, but despite reinstalls and tests with these components, I still cannot get past this CouchDB issue on my system... Ideas? Pointers? Suggestions? Has anyone successfully installed and used CouchDB 0.11.0 on an Ubuntu 10.04 system to RUN APPLICATIONS? I have come across multiple individuals who immediately respond 'yes, I have it installed - it works great' only to have them realize in the end (as I did) that just because Futon thinks things are working, doesn't mean CouchDB is properly handling ALL requests. Thank you for your time and assistance!

  • Spots appear in a rectangle area on screen, ubuntu gnome 13.04, nvidia driver

    - by frozen-flame
    I am using Ubuntu Gnome 13.04 with nvidia-310 driver installed. My GPU is GeForce GTX650. Strange spots freqently appear on screen, with following traits: Spots are restricted in one or two rectangle areas at any instant. When typing, the pattern of spots change. Possibly increase, or all disappear when one key pressed. Mouse movement also influences. This problem last within one boot. The only way can I get rid of this problem is to reboot. It can be detected as soon as entering desktop if it appears. Simultaneously, the "power off" option is lost in the top-right menu of Gnome3. Never such problem when using windows 7 on the same computer, neither ubuntu with Nouveou driver. Seldomly, half of the screen become black. I googled a lot. Similar conditions are described, but no confirmed solution. Uninstall-r einstall strategy does not work. Any clue solving this will be appeciated.

  • Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

    - by snitko
    I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either. Any ideas where should I be looking?

  • How to get a higher resolution on Ubuntu 11.04 using an intel chipset

    - by Saif Bechan
    I have a bit slow PC here, so I decided to put Ubuntu 11.04 on it. It use to run Windows Vista on a resolution of 1280x1024, so both my hardware and monitor support it. Now I'm on Ubuntu, but can only run 1024x768, and the screen is not that bright. Its like when you don't have the right drivers on a Windows machine. Now i'm new to linux, so I do not know what do do. I have an onboard Intel chipset i965. Maybe this is some useful information, I read something about it on a forum: lspci 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02) 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation N10/ICH 7 Family PCI Express Port 2 (rev 01) 00:1d.0 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation N10/ICH7 Family SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation N10/ICH 7 Family SMBus Controller (rev 01) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • How to change libcurl SSL backend from gnutls to openssl on Ubuntu server

    - by Jayesh
    I am getting gnutls specific errors in my Tornado webserver while processing Google OpenID SSL responses. One of the suggestions I got from Tornado mailing list is to try OpenSSL backend instead of gnutls. But it doesn't seem to be straightforward on Ubuntu server (11.10). On Ubuntu server, gnutls is provided by libcurl3-gnutls package and openssl curl support is provided by libcurl4-openssl-dev package. (I don't know why the later is named 4 and dev, but I couldn't find any other openssl+curl package in apt-cache search). I had libcurl3-gnutls installed by default, but not libcurl4-openssl-dev. So I installed the later and restarted Torando instances. But that didn't seem to work. I still got same gnutls errors. I found old discussions on curl mailing lists regarding the problems of supporting different SSL backends to libcurl, but didn't find exactly how is it done today. So far my guess is openssl is built into libcurl and gnutls is provided through separate package (that will explain why there is no libcurl3-openssl). But how do I make libcurl to pick up openssl backend and not gnutls? Is there some option in libcurl/pycurl API to do this? I tried uninstalling libcurl3-gnutls, but apt-get prompted that it will also remove python-pycurl along with it. So that won't do.

  • Ubuntu 10.04 freezing and Ctrl + Alt + Backspace does nothing but music keeps playing

    - by Bryce Thomas
    I'm having intermittent problems where the screen will freeze in Ubuntu. I've tried using Ctrl + Alt + Backspace to restart the X-server, though this does nothing. When the freeze occurs, there's a small square of black dashes around the mouse pointer - maybe 1 inch in size. These dashes look a lot like a 2d barcode. The rest of the screen looks normal, but I can't move the mouse and none of the keyboard shortcuts work to do anything. However, music that I begin playing before the freeze continues to play, which seems to indicate it hasn't stalled up completely. I've noticed a similar freezing problem when I'm using Windows 7. That is, I see the same barcode like dashes around the mouse pointer when it freezes up. So I'm guessing it's either a driver or hardware problem. I thought if it was a hardware problem though, the whole computer might stop working (i.e. music would stop playing)? The video card I am using is an Nvidia, and I believe it's in the 7600 range. In Ubuntu I have the drivers for the card set to the latest available (proprietary). Ideally I'd like to be able to continue using the proprietary drivers. Is there any known issues with the drivers for this model graphics card, or has anyone experienced the same problem and knows how to fix it?

  • Ubuntu Postfix email account with forward

    - by Mika
    I have an Ubuntu 12.04 server with Postfix installed. In Postfix installation I used this guide https://help.ubuntu.com/community/Postfix. I didn't go through all of that, just the sudo dpkg-reconfigure postfix part. I have created user accounts to my server and the users home directories contain a .forward file which have only one row the email address to forward to. I have defined dns A records for the names www.mydomain.com and mydomain.com But if I send an email to [email protected] it doesn't get forwarded. Actually I can't see any sign about any email ever visiting my server. My firewall is defined to allow incoming traffic for ports 80, 443 and 22. For outgoing traffic it allows ports 587 and 22. The exact definitions are below. Should I allow also outgoing http (port 80)? or maybe port 25? # Allow ssh in iptables -A INPUT -i eth0 -p tcp --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 22 -m state --state ESTABLISHED -j ACCEPT # Allow incoming HTTP iptables -A INPUT -i eth0 -p tcp --dport 80 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 80 -m state --state ESTABLISHED -j ACCEPT # Allow incoming HTTPS iptables -A INPUT -i eth0 -p tcp --dport 443 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A OUTPUT -o eth0 -p tcp --sport 443 -m state --state ESTABLISHED -j ACCEPT # Allow outgoing SSH iptables -A OUTPUT -o eth0 -p tcp --dport 22 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i eth0 -p tcp --sport 22 -m state --state ESTABLISHED -j ACCEPT # Allow outgoing emails iptables -A OUTPUT -o eth0 -p tcp --dport 587 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i eth0 -p tcp --sport 587 -m state --state ESTABLISHED -j ACCEPT Edits: I found lines from my syslog telling me that there were incoming traffic for port 25 which was blocked. The sender ip's for those packages were trustworthy, so I opened also port 25. Now I can see some Postfix logging in my syslog. It looks like it is at least trying to forward emails. I haven't yet received any forwarder emails into my gmail mail box.

  • adding a custom user folder on Ubuntu

    - by Narcolapser
    Question: How do you add a custom folder to the collection of user folders that come with Ubuntu? Info: I just loaded my netbook with Ubuntu Desktop 10.04LTS (Desktop because it is an aspire one and the Apocalypse seems to follow when ever i try to install netbook remix onto it). It comes with standard folders like Documents, Music, Pictures, Downloads(though this one doesn't appear until you actually download something), Videos, etc etc. These are handly little folders because they have little symbols on them and are nicely located in my file browser. it is basically like the folder lay out the windows had in vista. I do a lot of little programing on this computer so i have a folder in which i keep all these single kb code files. Obviously named "Code" that I keep in my home folder. But I would really like to it over listed next to my other user folders. In summary, how do you add a folder to the listing on the file browser. And, if possible, how do you give it an icon? (I understand fully that I will probably have to make said Icon) those two things are what I'm seeking to do. ~n P.s. please correct me if I'm using the wrong name. I just guessed and called them "User Folders" because they were folders the user uses. made sense. but if they have another name like "libraries" please say so. Thanks

  • Configuration Tuning for PostgreSQL 9.1 PostGIS 1.5 Ubuntu 12.04 Server

    - by Martin
    My server performance is poor. At times SSH, top, and other features or commands are very slow to respond, taking several seconds or more. A query that normally takes 5 minutes can sometimes take 30 minutes. The database is mostly being used to do a spatial query (grid and summarize) on approximately 500GB of stored data spread between 4 tables. Restarting the server works as a temporary fix, but cannot be used as a long term solution. Any suggestions for how to diagnose and solve my performance issues?

  • Virtualization in Ubuntu 9.10

    - by Jeff Dege
    I have an existing Centos 5 installation. I would like to upgrade to Ubuntu. Thing is, I don't want to be down for as long as it will take to get my entire environment moved over - software installed, connectivity configured, etc. I'd like to take it one step at a time. But I don't really want to keep rebooting back and forth from the new OS to the old OS. That's what I did last time I upgraded to a new OS, and it got old real fast. So, since my new MB is virtualization-ready (AMD Phenom II 945 quad-core), I figured I could create a virtual machine, under the new OS installation, that ran the old OS installation. The problem is that the documentation I've been able to find has been pretty sparse. I've found a lot of possibilities, and little info on which would be capable of doing what I want. I have a new Ubuntu 9.10 installation, and a second disk containing the Centos 5 installation. And I don't know where to go next. Any help would be appreciated.

I'm not exactly sure what I should do. I don't want to reinstall ubuntu, since I have it dual booted with Windows Vista and I don't want to risk anything on the Windows partition. What are your thoughts? EDIT: I've posted this on Ubuntu Forums and nobody ever responded so...yah

  • Ubuntu 12.04 open port 80 inside WLAN

    - by Eduard
    I have an nginx server running on ubuntu 12.04 that serves http through port 80 and https through port 443. Everything works fine if I access it from the same computer via localhost, 127.0.0.1 or the local IP 192.168.0.11. If I try to access the server from another computer in the same VLAN it does not work for http; it works for https. I have changed my nginx configuration to also listen to port 8000 for http; I can then access http from the other computer in the same VLAN via "http://192.168.0.11:8000". I also have a web server running on port 80 on a windows machine and can access it from another device in the same VLAN, therefore the router is not blocking incoming http traffic. The nginx process is run by root. I have used tcpdump and I see that packets are arriving to Ubuntu: 192.168.0.16.49735 192.168.0.11.80 and that some response is being given 192.168.0.11.80 192.168.0.16.49735 (I do not know what the response is though). There is no request arriving at the nginx web server (I have checked the access log). I have iptables empty. I have unsuccessfully tried to find a solution for a long time to this, it has now become a matter of happiness or bitterness :).
